Operating System (STORAGE) RAID Technology

RAID Technology:

RAID Technology isRAID (redundant array of independent disks; originally redundant array of inexpensive disks) is a way of storing the same data in different places (thus, redundantly) on multiple Hard Disk. This technology is basically a strategy which help to maintain a backup of data with Storage, the basic purpose to understand RAID is that server is also used as a tool to store data on the Cyber Space so this data present on the server is backed up using the Mirror techniques present in RAID Technology.

RAID Technology is basically divided into two components:

Striping

Mirroring

Striping is the process of storage of data on the storage disk in form of strips or lines of data, filling up one row at a time.

Mirroring is the process of creating a copy of data that has been stripped/stored inside the hard disk ie creating a copy of data stored so that even if the data crashed or gets corrupted can be restored.
